Which of the following are typical uses of networks?

• A. File sharing only
• B. Email and file storage only
• C. Web applications, IP telephony, video conferencing, interactive gaming, e-commerce
• D. None of the above

Answer: (C)

Networks enable devices to connect, share resources, and access services, which leads to a broad mix of common uses. The combination of web applications, IP telephony, video conferencing, interactive gaming, and e-commerce shows how networks support both everyday tasks (like browsing and emailing) and real-time, interactive services (such as voice calls, video meetings, and online gaming) as well as online transactions. These activities rely on data traveling quickly and reliably between users and servers across various locations, which is the essence of how networks function.

Using only file sharing captures only a small portion of what networks do. Limiting to email and file storage misses the real-time and interactive services that many users rely on. Saying none of the above would ignore the wide range of typical network-enabled activities that are already in use.
